Actuating mechanism for mechanically fireable flash devices

ABSTRACT

AN IMPROVED ACTUATING MECHANISM IN APPARATUS, SUCH AS A PHOTOGRAPHIC CAMERA, FOR SENSING THE CONDITION OF AND FOR FIRING A PERCUSSIVE FLASH DEVICE. THE FLASH DEVICE INCLUDES A LAMP AND A STRIKER (7) LODGED IN AN ENERGIZED POSITION FROM WHICH IT IS RELEASABLE TO FIRE THE LAMP. THE APPARATUS INCLUDES AN ACTUATING MEMBER (102) MOVABLE IN A FIRST DIRECTION TO FIRE THE DEVICE, AND IN A SECOND DIRECTION TO SPACE THE MEMBER FROM THE DEVICE. ENERGY FOR MOVING THE ACTUATING MEMBER IN THE FIRST DIRECTION IS TRANSLATED FROM A DRIVER (106) TO THE ACTUATING MEMBER BY A COUPLING LEVER (110) THAT FIRST MOVES INTO ENGAGEMENT WITH THE ACTUATING MEMBER TO DRIVE THE MEMBER IN THE FIRST DIRECTION, AND THEN MOVES OUT OF ENGAGEMENT WITH THE ACTUATING MEMBER TO PERMIT RETURN OF THE MEMBER TO THE SECOND DIRECTION.

PUBLISHED JUNE 22, 1971 An improved actuating mechanism in apparatus,such as a photographic camera, for sensing the condition of and forfiring a percussive flash device. The flash device includes a lamp and astriker (7) lodged in an energized position from which it is releasableto fire the lamp. The apparatus includes an actuating member (102)movable in a first direction to fire the device, and in a seconddirection to space the member from the device. Energy for moving theactuating member in the first direction is translated from a driver(106) to the actuating member by a coupling lever (110) that first movesinto engagement with the actuating member to drive the member in thefirst direction, and then moves out of engagement with the actuatingmember to permit return of the member to the second direction.
